That method required a displaying device with a determinate configuration, however, in this work we introduce a modification to be used with a modulator without a full 2π phase modulation. This variation is based on a binary joint power spectrum and it requires an interferometric process to obtain a single detection peak. We present a setup to carry out the whole process optically and we show experimental results that validate this new approach.8 p.application/pdfeng(c) Elsevier B.V., 2000Òptica de FourierReconeixement òptic de formesPantalles de cristall líquidFourier opticsOptical pattern recognitionLiquid crystal displaysinfo:eu-repo/semantics/article1862462019-12-12info:eu-repo/semantics/openAccess
